50mpg isn't too terrible, depends a lot on your driving style plus there's been a lot of cold and wet at the moment.
I've got the 1.6tdci in a mk6 fiesta so same engine but bigger displacement, that's doing 52mpg according to the readout on the dash but that's predominantly brisk b-road drivings.
No idea what the gearing is like on these so take the above as a rough reference I guess, but 42mpg sat at 70 sounds very low. Are the injector seals OK? Blow-by past those can make it run a bit rough as well.
